SPECIFICATION forming part of Letters Patent No. 444,262, dated January 6, 1891.

Application filed November 12, 1887. Serial No. 254,964. (No model.)

To all whom, t may concern: ter of the plates as and ci" and extending Be it known that I, ALBERT VAN NEss, a through and below the cross-beam a2 and citizen of the United States,residingatBeloit, communicating with an opening b in the in the county of Mitchell and State of Kansas, lower end of the mast, which opening leads 55 5 have invented certain new and nsefnllnr to one side of the mast, being designed for proveinents in Windmills; and l do hereby the passage of the rope or chain operating declare the following to be a full, clear, and the bucket. Mounted in brackets at suitable exact description of the invention, such as points upon the sides of the mast are idleis will enable others skilled in the art to which h2, bearing against the inner side of the ring 6o Io it appertains to make and use the same. a for the purpose of allowing the mast to turn This invention relates to an im roveiiient freel et acting as braces to hold it in an I n n 7 l I o e in windmills. upright position. To one side of the mast The object is to provide a simple and etnear the top is bolted a bracket b3, provided fective device by means of which the power with a bearing b4 for the wheel-shaft C, to the 65 I5 of the wind may be exerted to elevate water outer end of which is attached a wind-wheel, from deep wells or cisterns. which maybe any forni preferred. Upon the The invention consists in a combination rear of the shaft is loosely inonnted a drum D, and arrangement of various novel features to which is secured one end of the bucket-rope hereinafter fully described, and specifically cl, the rope being caused to be wound upon or 7o 2O designated in the claims. unwound therefrom, and the bucket conseln the accompanying drawings, in which quently operated by means of a clutch E, like letters of reference indicate correspond mounted upon the shaft at the inner end of ing parts in all the figures, I have illustrated the drum. The clutch colisists of an arm e, an embodiment of the invention,- in whichrigidly7 mounted upon the shaft and rotating 75 Figure l represents a side elevation of a with it, one end of which arm is bent inward windmill with my improvements applied. and overhangs a iiange d upon the drinn, Fig. 2 represents a horizontal section of the which forms a tread or surface for a strap e', same, the line of section being through the of thin flexible metal, secured at one end to top of the tower. Fig. 3 represents a plan the overhanging portion of the aiin e, its op- 8o View of the tower and mast, showing'the popositeeiid being attached to one end of a sition of its vanes. Fig. 4c is a rear view of bent rod c?, which also overhaiigs the iiange the clutch for throwing the drum into and CZ of the drum, the movement of this end of out of operation. Fig. 5 is a det-ail view of the bent rod being limited by means of a the arrangement of levers for operating the guide-rod secured to the arm e, and by which S5 Clutch, and Fig. G is a detail View of the means the lower portion of the arm @and the bucket and its automatic valve. bent rod are held in close relation to each Inthe drawings an ordinary tower is shown, other. The opposite end of the bent rod c2 (designated by A,) the tops of the standards of carries a pin e3, which works vertically in which are secured together by means of a slot, an opening (shown in dotted lines) in a 9o 4o ring ci, there being bolts passing through lugs lug cA1 extending laterally from the end of the a upon the outer side of the ring and the uparm e. The pin is secured near its lower end per end of each post. Upon a cross-beam a2, to a short bar c5, from which it extends upnear the top of the tower, is stepped a mast ward, the ends of the bar being formed into B by ineans of a plate a3, bolted to the crosstrunnioiis @6, upon which are hung links e7, 95 beam o2 and having a seat formed in it for the opposite ends of the linksbeing secured the reception of a lug formed on the bottom to a collar es, mounted loosely and sliding of a plate a4, secured to the lower end of the upon the shaft C, by which arrangement mast and being provided with a'iiaiiged outer when the collar eS is moved laterally upon the edge to better adapt its rigid attachment shaft C toward the drum D the bent rod e2, roo. 5o thereto. To the bottom of the mast may also to which the band e is attached, is drawn up be secured a tube h, passing through the cenand the band willbe tightened upon the flange and the drum caused to revolve with the shaft, and when the collar is moved in the opposite direction or away from the drum the hand is slackened from uponthe flange and the drum permitted to revolve indepeiulently of the shatt.

lt will be understood that when the slidingl collar e8 is in its normal position the ban d e does not contact with the flange of the d rum; but when thecollarismoved toward the drum it elevates the arm c? tlu'ough the medium of the links e and rod or pin c, connected. with the links and also with the arm e2, and as a consequence brings the lower inturned cud thereof in contact with the tlange of t-he drum, causing the band to tighten against the drum and revolve the same with the shaft, and when the collar is moved away from the drum it depresses or lowers the pin c and bent rod ci, consequently disengaging the lower end ot' the rod from the flange of the drum; or, in other words, the movement ot the collar c* toward the drinn elevates the bent rod and brings the lower end thereof in contact with the flange of the drum, and the movement of the collar from the drum lowers the bent rod and removes the lower end from engagement with the flange of the drum. The lateral movement of the collar and the consequent engagement of the drum are accomplished automatically, an d at the moment the bucket has reached its proper position, by means of a link c, attached to lthe collar e, the opposite end ot the fork heilig pivoted to a bar el", sliding in guides attached to the side ot the bracket b. To this bar is pivotally attached one end ot a short link c, its opposite end being pivoted to a weighted lever cl2, one arm of which is pivoted to the bracket, while the other arm engages one end of a rod e, extending downward and having an eye el* formed upon its lower end, through which the bucket-rope passes. Upon the bucket-rope is secured a stop e, placed at such point that when the bucket has been elevated to a snleienth eight the stop will be brought into contact with the lower end of the rod cl3, raising the rod and throwing the weighted lever over in the opposite direction, as shown in Fig. 5.

When the clutch is in gear, the links @Tand pin ci3 are in line, and the clutch thus locked in position. W'hen the lever el2 begins to rise, the stud el travels in the slot c in the end ot the rod e, and thus the weight on the lever passes its center of gravity before the collar begins to move upon the shaft C, the force ol' the falling lever then causing it to be moved immediately, and the drum, quickly released by the clutch, is free to revolve in the opposite direction by the weight of the falling bucket. A similar stop is secured upon the rope at a certain pointabove the other, l

so that when the bucket has reached the proper depth the stop will strike the eye upon the rod el, depressing the rod, which in turn causes the weighted lever to be drawn back to its original position, the clutch being again thrown into gear with the drinn and the rope again begins its ascent.

The bucket used is preferably cylindrical in shape and works in a tube placed within the well. Within this bucket F is a valvef, covering a lower compartment f', provided with an opening tor the inlet of water. ',lo this valve is attached a rod f, its opposite end being attached to one end of a small trip-lcvcrji", pivoted near the top of the bucket.

Depending from one end ot the beams of the tower at. a convenient point is a rod j", carrying 'upon its lower cud. a disk ft", which eucircles the rope and acts as a stop to trip the lcverfg, and thus operate the valve to discharge the bucket. rlhe upper end of the lever is curved outward, its opposite or lower cud occupying a position at the opposite side oi' the pivotal point to that occupied by the curved upper end, the lever being so shaped and placed for the purpose of allowing it to exert its greatest power at the moment its upper end strikes the disk f, when thegreatest resistance is to be overcome in starting the valve.

The speed oi the descending bucket is regulated by means of fans G, attached to the rear of the drum, the resistance to the air acting as a brake when the drum is in rapid motion.

The vane ll is hinged to the mast a suitable distance'below the wheel-shaft and is suitably braced thereon. A second vane h is rigidly secured and braced to the side of y the mast perpendicular to the line of the vane ll. The vane ll is provided with a spring h', secured to an arm extending from the mast. By this arrangement the speed of the wheel maybe controlled. Vv'hen the force ot' the wind becomes too great, the vane l1, is thrown partially around, the spring b allowing the large vane 1I to change its position in relation to the mast, and the wheel thus brought around in a line with the vanes presenting less surface to the wind.

Having thus fully described my invention, what I claim as new, and desire to Secure by Letters Patent, is

l. In a windmill, the combination, with the wheel-shaft, of a drum loosely mounted thereon for the operation of the bucket-rope, an arm mounted rigidly on the wheel-shat`t, a strap secured to one end of said arm and resting upon ailange formed upon the drum, the bent; rod carrying a pin in one end, its opposite end carrying the opposite end of the strap, said pin engaging a lug on said arm, and means whereby said pin is moved vertically in said lug, operating the bent rod, and causing the strap to bind upon or loosen from the flange on the drum, substantially as described.

2. In combination with a windmill, the clutch governing the revolution oi the drum for operating the bucket-rope, said clutch comprising an arm rigidly mounted on a IIO l Wheel-shaft and carrying one end of the'strap the bent rod, and a lever operated bya bucket-rope and connected to the collar7 whereby the collar will be moved laterally upon the wheel-shaft and the clutch be drawn into or out of engagement with the drum, substantially as described.

3. In a windmill, the combination, with the wheel-shaft, of a drum mounted loosely thereon, a clutch mounted rigidly thereon, a sliding rod mounted on the main frame and engaging a sliding collar on the main shaft, a weighted lever pivoted on the main frame, a

rod pivotally connecting said weighted lever to the sliding bar and having a slot in which the pivot on the Weighted lever moves, a rod pivoted at one end to the weighted lever and at its opposite end having an eye through which the bucket -rope passes, and stops placed at given points upon said bucket-rope, all combined and arranged to operate for the purpose of throwing the drum into and out of operation with the Wheel-shaft, and thus cause the winding and nnwinding of the rope thereon, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
